Does 3.75 have tyre pressure monitoring?

The direct TPMS on the current Mazda 3 is nice as it will show you the pressures while driving and you can see if the 3psi/4psi rule (depending who you believe) works.

On my old CX-5 with direct TPMS, you didn’t even know it was there. It may not even have been enabled. Twice a year, I would swap wheelsets and recode the new wheels to the car, but there was no positive confirmation this has been done, just the absence of a TPMS warning light.
